LONDON — Orcadian Energy has upped its estimate of technically recoverable resources from the proposed Pilot oilfield development in the UK North Sea by 18% to 97 MMbbl.
This is for a P50 case based on a polymer flood development scheme, with an upside estimate of 131 MMbbl.
It follows geophysical interpretation and geological and dynamic reservoir modelling work conducted with support from Axis and TRACS.
Orcadian has recently licensed and, with Axis’ support, interpreted newly reprocessed seismic data over Pilot, which led to the uplift to the developed area oil-in-place.
TRACS then constructed a range of geological scenarios while Orcadian performed multiple dynamic reservoir simulations to establish the new range of technically recoverable resources.
The geological models were designed to incorporate the full range of heterogeneity in evidence across the Pilot Field; the new full-field reservoir models were then calibrated to the results of the company’s polymer core flood experimental results.
These models have been tested with a range of possibilities for multiple parameters, generating a wide range of developed area recovery factors said to be consistent with the recovery factors adopted by Sproule in its 2021 Competent Persons Report on Pilot.
Orcadian CEO Steve Brown said, “This is the culmination of 18 months of work, which started with the interpretation of the newly reprocessed seismic from TGS…
“We are confident that this work has not only given us that understanding but will also provide an excellent basis for potential farm-in partners to evaluate the Pilot development in the coming months.”
